A Vanguard-classTitan that appears in Titanfall 2. It first appears during the training sequence at the beginning of the game, and is later dropped in for Jack Cooper after the destruction of BT-7274's original chassis. The current state of FS' original AI is unknown, as the chassis was dropped without an AI core so that Jack could place BT's inside of it.
The FS chassis is distinguishable from BT's original chassis by it's dark grey coloration.
